What does 'incidence' measure in epidemiology?
Answer: New cases of a disease over a defined time period
Incidence measures the rate of new cases of a disease arising in a population over a specific time period.
Which study design best establishes causation between a risk factor and a disease?
Answer: Randomized controlled trial
A randomized controlled trial (RCT) is the gold standard for establishing causation because random allocation minimizes confounding variables.
What is the main purpose of a needs assessment in dental public health?
Answer: To identify oral health problems and resources in a community
A community needs assessment identifies the oral health status, disease burden, and existing resources to plan appropriate public health interventions.
Which federal program provides dental coverage for low-income children in the United States?
Answer: CHIP/Medicaid
Medicaid and the Children's Health Insurance Program (CHIP) provide dental benefits to eligible low-income children across the US.
Which preventive measure has the highest cost-effectiveness for caries prevention at the community level?
Answer: Community water fluoridation
Community water fluoridation is consistently ranked as the most cost-effective public health measure for caries prevention, delivering benefits to entire populations.
What is 'sensitivity' of a diagnostic test?
Answer: Ability to correctly identify those with disease (true positive rate)
Sensitivity is the true positive rate — the proportion of people with the disease who test positive, reflecting the test's ability to detect disease.
